Sergei Petrunia	cbbe4971b6	MDEV-21887: federatedx crashes on SELECT ... INTO query in select_handler code ... - Don't try to push down SELECTs that have a side effect - In case the storage engine did support pushdown of SELECT with an INTO clause, write the rows we've got from it into select->join->result, and not thd->protocol. This way, SELECT ... INTO ... FROM smart_engine_table will put the result into where instructed, and NOT send it to the client.	2020-03-07 01:14:41 +03:00
